Qhia koj yuav ua li cas txo qhov kev ntsuas qhov yuam kev ntawm thermocouples

1, Yog vim li cas rau qhov yuam kev
1. Qhov cuam tshuam ntawm thermocouple qhov tseeb ntawm kev ntsuas qhov yuam kev. Qhov no yog hais txog cov yam ntxwv ntawm thermoelectric, stability, thiab uniformity ntawm thermocouples.
2. Qhov cuam tshuam ntawm cov yam ntxwv indexing ntawm cov cuab yeej tso saib thiab ntsuas Circuit Court ntawm kev ntsuas qhov tseeb.
3. Tom qab tso cov thermocouples rau ntawm qhov chaw kuaj, qhov chaw ntsuas kub ntawm qhov chaw kuaj tau hloov pauv. Nyob rau lub sijhawm no, qhov ntsuas kub qhia los ntawm qhov chaw thermocouple tsis sib npaug ntawm qhov ntsuas kub thaum lub thermocouple tsis tau teeb tsa. Qhov yuam kev los ntawm thermal conductivity tom qab nteg nto thermocouples yog hu ua "thermal conductivity yuam kev". Nws yuav tsum tau hais tias qhov tseeb ntawm lub thermocouple nws tus kheej ua rau me me yuam kev piv rau thermal conductivity yuam kev. Ntev npaum li cov ntaub ntawv zoo thermoelectric electrode raug xaiv, cov yam ntxwv ntawm lub tshuab hluav taws xob yog qhov ruaj khov, thiab cov khoom siv thermocouple thiab cov cuab yeej siv tau zoo sib xws, qhov tsis raug los ntawm qhov tseeb ntawm lub thermocouple nws tus kheej feem ntau tuaj yeem tsis quav ntsej. Txawm li cas los xij, thermal conductivity yuam kev yog qhov nyuaj rau zam thiab tseem ceeb heev rau kev ntsuas kub ntawm qhov chaw.
4. Yog hais tias qhov kub thiab txias ntawm cov khoom ntsuas yog nyob rau hauv lub xeev hloov, qhov yuam kev tshwm sim los ntawm dynamic teb lag ntawm lub thermocouple mus rau qhov kub thiab txias yog hu ua "dynamic teb yuam kev". Tom qab txhim kho lub thermocouple ntawm qhov chaw sim, qhov chaw ib puag ncig kuj tseem yuav tsim hluav taws xob hloov hluav taws xob rau ntawm lub tshuab hluav taws xob electrode. Piv txwv li, qhov sib txawv ntawm qhov chaw blackness ntawm cov khoom kuaj thiab cov thermoelectric electrode generates hluav taws xob hloov hluav taws xob. Hom kev ua yuam kev no yog hu ua "radiation heat transfer error"
2, Qhov yuam kev tshwm sim los ntawm kev teeb tsa tsis raug thiab tso txoj hauv kev.
Hauv cov ntsiab lus, kev ntsuas qhov yuam kev ntawm qhov chaw hnav-tiv taus thermocouples feem ntau yog tshwm sim los ntawm rau yam uas tau hais los saum toj no. Txhawm rau txiav txim siab tag nrho kev ntsuas qhov yuam kev, kev ntsuas kev ua yuam kev ntxiv yog qhov tsim nyog, uas tuaj yeem txiav txim siab los ntawm kev sim thiab suav.

3, Kev ntsuas thiab cov txheej txheem los txo qhov ntsuas qhov yuam kev
1. Xaiv cov ntaub ntawv thermoelectric electrode nrog cov thermal conductivity me me thiab zoo txoj kab uas hla kom ntau li ntau tau nyob rau hauv cov xwm txheej ntawm txhua yam muaj zog. Txoj kab uas hla ntawm cov thermoelectric electrode feem ntau yog xaiv los ntawm 0.2 mus rau 0.5 millimeters.
2. Thaum tso cov thermocouples saum npoo, qhov cuam tshuam ntawm convection yuav tsum raug tshem tawm ntau li ntau tau. Piv txwv li, thaum muaj roj ntws ntawm qhov chaw sim, yog tias muaj kev tso cai, cov thermocouple tuaj yeem faus. Tab sis nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov zawj qhov loj me yuav tsum me npaum li qhov ua tau, thiab tom qab embedded, qhov chaw ntawm cov khoom ntim yuav tsum tau polished kom qib nrog qhov ntsuas qhov chaw.
3. Thaum lub sij hawm kev teeb tsa, sim tsis txhob ua kom qhov kub thiab txias ntawm qhov chaw kuaj thiab cov duab geometric ntawm cov khoom kuaj.
4. Cov lus teb dynamic ntawm qhov xaiv qhov chaw thermocouple yog qhov zoo dua thaum hloov pauv hauv kev ua haujlwm thiab kev ntsuas tam sim.
5. Isothermal nteg tuaj yeem txo cov thermal conductivity yuam kev. Lub thermoelectric electrode tom qab ntsuas qhov kawg yuav tsum tau muab tso rau ntawm qhov ntsuas qhov ntev ntawm qhov tsawg kawg yog 50 npaug ntawm txoj kab uas hla ntawm lub thermoelectric electrode. Cov rwb thaiv tsev thermoelectric raws li qhov chaw sim yuav tsum nyias thiab cov khoom siv yuav tsum muaj cov thermal conductivity zoo los txhim kho cov thermal conductivity ntawm qhov chaw kuaj thiab cov thermoelectric electrode. Tom qab cov thermoelectric electrode ua rau qhov ntsuas qhov saum npoo, cov txheej txheej rwb thaiv tsev ntawm cov thermoelectric electrode yuav tsum yog tuab dua thiab zoo insulated kom txo tau cov cua kub dissipation ntawm cov thermoelectric electrode ntawm cov roj. Yog hais tias qhov kev tiv thaiv ntawm thermocouple ntsuas Circuit Court loj dhau, txoj kev sib tshooj tuab thiab nyias thermoelectric electrodes tuaj yeem siv tau. Thaum xaiv qhov sib tshooj ntawm tuab thiab nyias thermoelectric electrodes, kev saib xyuas yuav tsum tau them rau qhov sib xws ntawm cov yam ntxwv thermoelectric kom ntau li ntau tau.
6. Thaum ntsuas qhov kub thiab txias, peb ib txwm cia siab rau qhov raug siab. Txhawm rau txo qhov ntsuas qhov yuam kev, kev ntsuas tsim nyog tuaj yeem ua raws li kev ua haujlwm tiag tiag kom tau txais cov txiaj ntsig kev ntsuas txaus siab.
7. Kev ntsuas qhov kawg ntawm qhov chaw thermocouple yuav tsum muaj kev sib cuag zoo thermal nrog qhov ntsuas qhov saum npoo, thiab txoj kev sib cuag yuav tsum tau vuam (xa mus rau vuam pub rau ntawm qhov ntsuas qhov chaw). Vuam cov ntsiab lus yuav tsum tsis txhob muaj slag inclusions los yog ntxeem tau daim txhuam cev zoo li cov qauv. Cov ntsiab lus vuam yuav tsum me me thaum ua kom muaj zog txaus. Txhawm rau txhim kho qhov vuam lub zog ntawm qhov ntsuas qhov ntsuas qhov kawg, qhov vuam ib feem ntawm cov thermoelectric electrode tuaj yeem ua rau me ntsis biased.
8. Kev ntsuas qhov kawg ntawm lub siab lub caij nplooj ntoos hlav thermocouple yuav tsum nyob ze li sai tau rau qhov ntsuas qhov chaw. Rau kev ntsuas qhov kawg, qhov ntsuas qhov kawg tuaj yeem ua kom flattened. Thaum lub thermal conductivity ntawm cov khoom kuaj tau qis heev, lub phaj ntim nrog cov thermal conductivity zoo tuaj yeem siv.
9. Cov ntaub ntawv thermoelectric electrode yuav tsum muaj cov khoom siv hluav taws xob zoo, ruaj khov, thiab sib xws. Ua ntej ntau lawm, cov khoom siv thermoelectric electrode yuav tsum tau ntsuas kom ntseeg tau tias kev ua tau zoo thiab txhim khu kev qha.
